Transflective liquid crystal display device having a monochrome reflection mode and full color transmission mode

Abstract

A liquid crystal display device includes a liquid crystal panel including liquid crystal interposed between a pair of substrates facing each other and pixels, each pixel having a plurality of subpixels corresponding to different colors, an illumination device that is provided at one side of the liquid crystal panel to irradiate illumination light onto the liquid crystal panel, a color filter that is provided on one substrate of the pair of substrates where the illumination device is provided and in which a plurality of colored layers for different colors corresponding to the subpixels are arranged, a reflecting film that is provided at the liquid crystal side with respect to the color filter, and transmissive portions that overlap the colored layers to transmit illumination light.

1. A liquid crystal display device comprising:
 an illumination device that outputs illumination light; and 
 a liquid crystal panel that receives the illumination light from the illumination device, the liquid crystal panel including:
 a first substrate; 
 a second substrate disposed in between the first substrate and the illumination device; 
 liquid crystal interposed between the first and second substrates; 
 a pixel having subpixels corresponding to different colors, each sub-pixel including a reflective portion and a transmissive portion; 
 a first color filter corresponding to one of the subpixels, the first color filter being disposed between the liquid crystal and the second substrate; 
 a second color filter corresponding to another one of the subpixels, the second color filter being disposed between the liquid crystal and the second substrate at a position adjacent to the first color filter; and 
 a first reflecting film provided in between the liquid crystal and the first color filter; 
 a second reflecting film provided in between the liquid crystal and the second color filter, the second reflecting film being separated from the first reflecting film by a gap; and 
 
 a light-shielding layer provided between the first and second color filters at a position that overlaps the gap between the first and second color filters at a position that overlaps the gap between the first and second reflective films, the light-shielding layer having a broader width than the gap between the first and second reflective layers, 
 wherein no color filter is disposed between the first substrate and the first reflecting film or the second reflecting film and the first and second reflecting films directly contact the light-shielding film. 
 
   
   
     2. The liquid crystal display device according to  claim 1 ,
 wherein the reflecting film is laminated directly on the first and second color filters. 
 
   
   
     3. The liquid crystal display device according to  claim 1 ,
 wherein the reflecting film has a light-scattering function. 
 
   
   
     4. The liquid crystal display device according to  claim 1 ,
 wherein the light-shielding layer contacts the first color filter and the first reflecting film overlaps a portion where the light-shielding layer contacts the first color filter. 
 
   
   
     5. An electronic apparatus comprising the liquid crystal display device according to  claim 1 . 
   
   
     6. A liquid crystal display device comprising:
 an illumination device that outputs illumination light; and 
 a liquid crystal panel that receives the illumination light from the illumination device, the liquid crystal panel including:
 a pixel having a plurality of subpixels corresponding to different colors, each sub-pixel including a reflective portion and a transmissive portion; 
 a first substrate; 
 a second substrate disposed in between the first substrate and the illumination device, the second substrate being formed with a concave portion in a surface thereof that faces the illumination device, the concave portion extending continuously across the plurality of subpixels of the pixel; 
 liquid crystal interposed between the first and second substrates; 
 a first color filter corresponding to one of the subpixels, the first color filter being disposed within the concave portion in the second substrate; 
 a second color filter corresponding to another one of the subpixels, the second color filter being disposed within the concave portion in the second substrate with the first color filter; and 
 a reflecting film provided in between the liquid crystal and the first and second color filters 
 wherein no color filter is disposed between the first substrate and the reflecting film. 
 
 
   
   
     7. The liquid crystal display device according to  claim 6 , wherein the first color filter and the second color filter contact each other, the reflecting film overlapping a position where the first and second color filters contact each other.
